Description
Technical field
The invention belongs to build base material technical field.It is levelling more particularly, to a kind of gypsum base with concrete powder
Putty and preparation method thereof.
Background technology
In order to improve living environment and comfort level demand, secondary decoration is more and more common in house ornamentation market at present, has wide
Wealthy market prospects, but have extremely harsh requirement to the construction period of finishing, especially indoor wall leveling is handled, it is desirable that
Construction procedure simplifies as far as possible, curing cycle is short, will not occupy the valuable construction time etc..Therefore, domestic building materials use at present
Position by it is newly-built turn to refresh based on, construction requirement is high, and the construction time is short, and existing cement base leveling putty is susceptible to sky
The problems such as rousing, crack, falling off, and curing time is long.Existing gypsum powder on the market also has very much, but most is low
A series of problems, such as holding product, often will appear rust spot, xanthochromia, shedding, blistering.
In order to solve the above technical problem, the present invention provides one kind using desulfurated plaster as major gelled material, building concrete powder
The gypsum base leveling putty prepared for filler.
Invention content
First of the present invention is designed to provide a kind of gypsum base leveling putty with concrete powder.
Second object of the present invention is to provide a kind of preparation method of the gypsum base leveling putty with concrete powder.
A kind of gypsum base leveling putty with concrete powder, the gypsum base leveling putty include the original of following parts by weight
Material：
The desulfurization gypsum powder be after coal fired power plant flue gas desulfurization generated waste residue by half water stone of β types made of calcining
Cream；β-CaSO in the desulfurization gypsum powder4·1/2H2Mass percent >=80%, 0.045mm square hole screen screen over-size of O≤
10%；β-CaSO in desulfurization gypsum powder4·1/2H2The content of O is generally higher than 80%, and for the natural gypsum, of the invention is de-
Sulphur land plaster impurity is less, intensity higher, is more suitable for the low filler of collocation this intensity of concrete powder to make leveling putty.
The building concrete powder be building concrete slag and brick slag by crushing, sieving and except iron handle it is inorganic at
Point；The grain size of the building concrete powder is 100-300nm.Ca is mainly contained in building concrete powder2SiO4、 Ca2Co3、CaSO4·2H2O、
SiO2Etc. inorganic constituents, the inorganic constituents be inertia or micro- active filler.
Further, the polymer dispersion powder is styrenic-acrylic latex powder, Acrylic emulsion powder, vinyl acetate-
One or both of ethylene latex powder.The polymer dispersion powder that is added in inventive formulation meet after water dissolution with the silicon in gypsum
Hydrochlorate reacts, and forms crosslinked organic water-fast film between mortar particulate interspaces, chlorion in mortar is prevented to be moved to water
Mortar surface, and then the gypsum base leveling putty prepared is avoided to turn yellow.
Further, the water-retaining agent is in hydroxypropyl methyl cellulose sodium, carboxymethyl cellulose, hydroxymethyl ethylcellulose
One or two.There are two types of effects for the water-retaining agent of the present invention：First, by mortar fluidised form paste, construction feel is provided, second is that
The moisture in mortar is lockked, free moisture is prevented to expand calculation into foundation wall and air, is β-CaSO4·1/2H2O is transformed into CaSO4·
2H2O provides the crystallization water, avoids " ashing " phenomenon.
Further, quickly due to gypsum mortar solidification, generally only 5-10min, the present invention, which adds retarder, can make stone
The setting time of cream mortar becomes 60-120 minutes, suitably can the construction time with offer.The retarder is animal protein, lemon
One or both of lemon acid, sodium citrate.
Further, due to gypsum leveling putty be it is not water-fast, hydrophober that the present invention adds on the one hand can to avoid
When construction paint priming paint, the large quantity of moisture in priming paint enters in gypsum leveling putty, by CaSO4·2H2O dissolves, and leads to gypsum
Putty and foundation wall delamination；On the other hand the precipitation that calcium ion in gypsum base leveling putty can be prevented, causes gypsum base levelling greasy
The strength reduction of son.The hydrophober is silylation hydrophober or calcium formate.
Further, the mould inhibitor is the loose powder series bactericidal agent of click.Gypsum base leveling putty of the present invention adds mould inhibitor
Since gypsum is weakly acidic, and the starch ether and retarder added in gypsum base leveling putty can provide nutrients for bacterium
Matter；Therefore be conducive to bacterium production；The mould inhibitor that the present invention adds can be to avoid slow mouldy in the drying of plum rain season metope.
Further, it in order to improve the anti-sag ability of leveling putty, adds and forms sediment in the gypsum base leveling putty of the present invention
Powder ether；The starch ether is hydroxyalkyl starch, carboxymethyl starch, the one or two of cationic starch.
Further, the present invention avoids the coagulant of intensity to extend presetting period of gypsum during storage
For the one or two of calcium oxide, calcium hydroxide.Since presetting period extension can cause gypsum intensity to gypsum during storage
Loss, therefore in order to reduce the gypsum presetting period, the present invention adds coagulant in gypsum base leveling putty, which can make
Gypsum aquation in crystallization process is rapider, increases substantially putty intensity.
Further, the anti-yellowing agent is one or more in silicate, hydrophobic organosilicon.This is because free calcium from
The calcium silicates that son is formed with silicate, more resistant to water, can prevent calcium ion that xanthochromia is precipitated than calcium sulfate.
A kind of preparation method of gypsum base leveling putty, it is specific as follows：By desulfurization gypsum powder, building concrete powder, water-retaining agent, resist
Xanthochromia agent, polymer dispersion powder, hydrophober, retarder, technical grade tartaric acid, starch ether, coagulant and mould inhibitor put into sand
Slurry stirrer for mixing stirs evenly, and obtains gypsum base leveling putty.
Beneficial effects of the present invention are as follows：
1, since formula is rich in gypsum composition in the formula of gypsum base leveling putty of the present invention, so that gypsum base is levelling
Putty has loose porous, and thermal coefficient is small, the good feature of heat insulation property.
2, gypsum base leveling putty of the invention has good workability due to being added to water-retaining agent and starch ether
And the characteristics of water-retaining property；The directly upper wall plastering after mixing by the gypsum base leveling putty of the present invention and water, feel is very light, batch
Depending on construction thickness is applied by Base Smoothness, maximum gauge can paint 3cm, and anti-slipping property is good, and labor intensity is low, spillage of material
Small, construction area is more.
3, the coat of plaster that gypsum base leveling putty using the present invention is formed, fast solidifying, curing cycle is short, can be significantly
Working efficiency is improved, the duration is saved.
4, gypsum base leveling putty fire protecting performance of the invention is good；When fire occurs, gypsum hardenite has mass crystallization
Water releases under heat effect, forms steam, blocks the sprawling of flame, while being absorbed largely in entire dehydration
Heat, to improve fire protecting performance.
5, gypsum base of the invention has respiratory function：Desulfurized gypsum base thermal insulation mortar has automatic moisture absorption and automatic release water
Divide function, so as to which indoor humidity control within optimum range, is created comfortable family life environment.
